Setting a Different Port to Connect to the Cato PoP

  • Updated

Overview

Oftentimes, the Socket can sometimes disconnect, because the government requires ISPs to restrict using UDP port 443. You can configure the Socket instead to use UDP port 1337.

Solution 

Starting with Socket version 12, there is an easy method to set a different port to establish the tunnel with Cato PoPs.

To change the port:

  1. Log in the Socket WebUI.
  2. Browse to the Cato Connection Settings tab: Screen_Shot_2021-11-10_at_10.55.30.png

  4. Click Reconnect to apply the changes to the Socket. (You can also restart the Socket.)
    The Socket establishes the DTLS tunnel using the 1337 UDP port.
